OTC Jewelry Mark

What is an OTC Jewelry Mark?

An OTC jewelry mark is a stamp or inscription found on pieces of jewelry, indicating that the item was produced or distributed by OTC International, Ltd., a company established in 1977 and headquartered in New York City.

Identifying OTC Jewelry Marks

OTC jewelry marks can vary in appearance, but they often include the following elements:

  • The initials “OTC”: This is the most common identifier and can be found alone or combined with other elements.
  • “Italy”: Some OTC pieces, particularly those crafted from silver, may also feature the inscription “Italy” to indicate the country of origin.
  • “Sterling Silver” or “925”: This mark signifies that the piece is made of sterling silver, an alloy containing at least 92.5% pure silver.
  • Other markings: Occasionally, OTC marks may include additional information, such as a copyright symbol, design number, or hallmark.

History and Significance

OTC International primarily deals in silver and gold jewelry, offering a diverse range of styles, from classic and timeless to contemporary and trendy. Their pieces are often found in vintage and pre-owned markets, reflecting their long-standing presence in the jewelry industry.
